Production Introduction:

STORM-7300 Electric Marine Horn incorporates three main functions,marine horn,cabin interphone and general alarm.It has advantages of high acoustic pressure,comprehensive functionality,high reliability,long service life and simple installation.

 

The high power electric horn is able to make 131 dB @1m acoustic pressure to achieve one nautical mile effective audibility range.It is applied for vessel over 20 meters but under 75 meters in length.It can work under serious marine environments with excellent outdoor performance,anti-water/dust (IP56),corrosion and high-low temperature resistance. Patent No. ZL201020522870.2,ZL201030282705.X

 

With integrated chip control,the horn makes stable frequency sound.It incorporate a push ‘at-will’ button to produce blast manually.Besides there is one automatic fog horn button,which can produce prolonged and short blast codes repeatedly according to IMO/SOLAS requirement.The hand-held microphone can make PA talk both outward sea and interphone talk between navigation bridge and cabins.It incorporate one general emergency alarm button,which can make emergency alarm sound both on the horn and cabin interphone speakers under emergency situation.

Installation:

STORM-7300 electric marine horn includes mainly the electric horn and control amplifier.

 

1.Electric Horn Installation:

Pls combine the horn and STORM-7300 sound driver by the flange connector with screws.

Pls take care if the rubber gasket and metal filter be put in between the horn and the flange connector.Mounting installation brackets on the bottom of sound driver by twisting screws. The horn is installed outside cabin,pls make sure there is no obstacle in front of horn.Horn outline measurement.

 

2.Control Amplifier Installation:

The control amplifier need installing inside navigation bridge.We can fix it on a flat surface by

brackets on its sides or embed it into ship bridge console with fixing screws on control interface

quadrangle.Control amplifier outline measurement.

 

3. Horn & Amplifier Connection

Connect amplifier DC power input port with DC power source,pls take care if concerning positive and negative electrode connected correctly.Horn & amplifier connection.

 

By two multi-strand copper wire,connect horn output port with input lines of electric horn,which has no electrode requirement.1.0 mm2 cross sectional area is s ested,if the wire length under 50 meters.The wire cross sectional area need enlarging with the length increasing.The effective wire length should not exceed 500 meter.

 

4.Cabin Speaker Installation

Refer to diagram 3.Connect two Cabin speakers into 3.5mm ports on amplifier back,‘Cabin Speaker I’ and ‘Cabin Speaker II’.We can cut the 3.5mm plug to lengthen wire according to practical distance demand.

 

Operation Introduction:

STORM-7300 Electric Marine Horn incorporates three main functions,marine horn,cabin interphone and general alarm.First of all,switch the power on,the power indicator lighted.Follow the detailed operation way as below.

 

 

1.Electric Horn Operation

Turn ‘Transfer Switch’ to ‘Horn’,then the cabin speaker will be turned off.

 

(A)Manual Horn

Push ‘Manual Horn’ and hold it,button light on,the horn will produce blast at-will,once release the button the sound will stop,button light off.

 

(B)Auto Fog Horn

According to IMO/SOLAR requirement,when navigate or stop in or near an area of restricted visibility,like in fog,a vessel must produce regular prolonged and short blast codes to warn an approaching vessel the possibility of collision.

 

Push the ‘Auto Fog Horn’ one time without holding,button light on,the horn will produce regular prolonged and short blast codes repeatedly until push the button again to stop it,button light off.

 

(C)PA Talk Outward

When ‘Transfer Switch’ on ‘Horn’,we can use the microphone to make PA talk outward sea.

 

2.Cabin Speaker Operation

Turn ‘Transfer Switch’ to ‘Cabin Speaker’,then the electric horn will be turned off.

 

When ‘Cabin Speaker I’ button light on,we can use the microphone to talk to concering cabin,the sailor in cabin can also reply to navigation bridge through direct talking to cabin speaker without other operation,the sound will be played by internal speaker in control amplifier.When push ‘Cabin Speaker II’,button light on and ‘Cabin Speaker I’ button light off,we can make interphone talk with cabin speaker II area as way above.

 

3.General Alarm

When emergency situations occur,such as fire,machine failure,gas leak and man overboard,push ‘General Alarm’,button light on,one emergency alarm sound will be triggered both on electric horn and cabin speakers to warn the sailors.Push the button again to stop alarm,button light off.

 

Repair

When the equipment not work or function abnormally,pls check as below steps:

 

1.Switch power on without indicator light on

(A)Check if input power voltage DC24V,if positive and negative electrode connected correctly.

(B)Check if input fuse burned.Input fuse 15A.

 

2.Push horn button but no sound make

(A)Check if ‘Transfer Switch’ on ‘Horn’.

(B)Check if connection in correct port,if any circuit or broken circuit occur on wires between horn and amplifier.

 

3.Cabin speaker not work

(A)Check if ‘Transfer Switch’ on ‘Cabin Speaker’.

(B)Check if the cabin speaker plug in amplifier firmly.

(C)Check if circuit or broken circuit occur on wires between cabin speaker and amplifier.

If after checking above concerning clauses,the equipment still with problem,pls contact Mantangcai Electronics Co.,Ltd. as soon as possible.Pls do not open and repair the equipment without authorization,otherwise we would not be responsible for what damage or loss casue by this behavior.

 

 

Maintenance & Precautions

1.The input power must be correct DC24V.

2.The power electrode can not be connected in reverse.

3.The electric horn installation brackets must be fixed firmly.

4.Prevent the control amplifier away from humidity.

5.Regular check operation situation.

6.Regular clear up horn inside and outside.

7.Keep the product manual in case repair or disassemble.
